There is no single authority that can tell you what a full spectrum light is or isn’t as the definition is somewhat soft. However, most sources will agree that a full spectrum light bulb is one that attempts to reproduce, as closely as possible, the qualities of natural daylight.
A perfect full spectrum light, according to this definition, would then have a color rendering index (CRI) of 100. Using a spectrometer, one can ascertain how closely a light bulb will replicate the apparent nature of daylight, but for most intents and purposes, if, to the human eye, the bulb reproduces sunlight, it will be marketed as a full spectrum bulb.
Why then, does this matter?
There are a lot of sources out there touting the benefits of full spectrum bulbs because of their apparent similarities to sunlight. Consider some of these more common claims, below, and see what you think.
1.Full spectrum light bulbs may be able to improve mood
According to a report by the National Lighting Product Information Program (NLPIP) regarding the impacts of full spectrum lights, they may have the potential to improve mood. The report took into account the claims of respondents based on perceived impacts as a result of the lighting, and a significant majority of respondents claimed that exposure to full spectrum light not only improved their moods but also their mental focus, clarity, and productivity. Of course, this hinges on the validity of the respondent’s claims and does not account for other controls, but it is something to bear in mind. There are a lot of claims about full spectrum lights that have not been fully investigated, and though these are among them, if the respondent’s claims can be trusted, there may be some truth to the allegations regarding light therapy and mental health.
2.They may be able to boost retail sales
It has also been claimed that full spectrum light bulbs may be able to positively impact consumer behavior within retail locations, helping to encourage sales. This is good news for retail owners and operators who need a creative way to positively affect the moods and actions of their customers. In the same report published by the NLPIP, over half of respondents claimed that retail sales increased as a result of full spectrum lighting. Some retailers around the country, such as Wal-Mart, have also reported boosts in sales as a result of the implementation of daylighting.
3.They can be useful for indoor gardeners
Make no mistake about it, real sunlight is the best light for plants, bar none. However, for some gardeners, and those attempting to grow plants inside during the winter, the sun just doesn’t come out to play frequently enough to keep plants healthy.
It’s possible that some full-spectrum grow lights may be able to promote healthy growth in plants, even during the winter months. Higher intensity, full spectrum grow lights may be beneficial for those with houseplants who are struggling to find ways to keep them green and full during the winter months. Plants will stretch out and become weak without access to adequate sunlight, but a full spectrum light, though not a perfect solution, may help to stall this problem.
4.On a similar note, they can stimulate vitamin D synthesis in people
Vitamin D is a fat-soluble vitamin that supports the immune system, the mood, and overall health. In order to synthesize it, your skin needs to be exposed to a certain wavelength of light - namely, UVB. If the full spectrum bulb in question emits light that falls within the UVB wavelength range, then it may be able to help promote vitamin D synthesis, which can be beneficial for those living at high latitudes with decreased exposure to sunlight in the winter.
5.Full spectrum light bulbs display colors more faithfully
Finally, we have one benefit that is pretty much incontestable. Whereas we can only present the other benefits in this article with the caveat that they are alleged claims, full spectrum lights are the superior light source for color rendering index (CRI) which is an indication of how faithfully the light represents colors.
For those in design or fashion, or for artists, full spectrum lighting can make assessing and evaluating colors easier, efficient, and more accurate. The color temperature of the lights themselves will not interfere with the colors perceived, allowing them to be assessed as accurately as possible.
Alleged health benefits aside, what is certain is that full spectrum light bulbs emit light that replicates the natural light of the day, despite the disparities on the electromagnetic spectrum.
